the volcanic features associated with the more 

 recent cinder cones and lava flows. 



From here the party went to the Grand 

 Canyon, making a three-days' trip down in 

 the canyon with pack outfit, after which the 

 journey eastward to the crossing of the Little 

 Colorado and northward over the desert along 

 the Echo and Paria cliffs, was begun. This 

 proved to be the most strenuous part of the 

 whole summer campaign, not so much because 

 of lack of water — for which emergency due 

 provision had been made — as because of the 

 failure to secure sufficient feed for the five 

 head of horses. From the Grand Canyon to 

 the town of Kanab in southern Utah, a dis- 

 tance of more than 250 miles by the route 

 traversed, the only grain available was a little 

 corn at Tuba and one feed of oats at Lee's 

 Ferry. The weather was intensely hot, the 

 roads heavy with sand in many places, while 

 grass fit for the horses to graze upon was only 

 found at occasional places. As a result the 

 horses got in poor condition, short days of 

 travel and long rests were necessary, so that 

 a large amount of time was consumed in this 

 part of the journey. Kanab was reached on 

 August 6. 



From Kanab the party went north to Upper 

 Kanab in order to visit the great terraces of 

 the high plateaus of southern Utah. Return- 

 ing to Kanab, a trip was then made to the 

 southwest into the Toroweap Valley and the 

 Mt. Trumbull region, for the purpose of 

 tracing the relations of the Sevier and Toro- 

 weap faults, and the associated volcanic fea- 

 tures. Eetuming as far as Pipe Spring, the 

 party then turned westward, descending the 

 Hurricane fault scarp west of Workman's 

 Spring, and turning northward to the Virgin 

 River. A delay of three or four days at this 

 point was caused by a flood which was said 

 to be the greatest ever known in the river's 

 history. 



Northward from the Virgin River the route 

 passed along the margin of the Great Basin 

 Province, at the foot of the western rim of 

 the High Plateaus, through the towns of 

 Toquerville, Beaver, Porowan, Holden, Nephi, 

 etc. Good progress was made over splendid 



roads, notwithstanding frequent stops for side 

 trips into many of the canyons which made 

 possible a study of the northward continua- 

 tion of the Hurricane fault, the character of 

 the great Tertiary series and the volcanic beds, 

 the undoubted evidence of recent faulting and 

 other points of geologic and physiographic 

 interest. 



The outfit was sold in the towns of Prove 

 and American Fork, just south of Salt Lake 

 City. From the latter point Dr. Shimer went 

 to the Yellowstone National Park for a few 

 days, while Professor Johnson returned east 

 by way of Butte, Montana. Mr. Decker will 

 spend some time in the Bingham and Park 

 City mining districts. 



A detailed statement of the studies made in 

 connection with the expedition, including re- 

 ports on several special problems, will be pub- 

 lished in the course of the winter.
